    摘要: A joining equipment in which a neural network is employed for controlling a joining process. A dynamic analog model is used for neuron elements configuring the network. The equipment includes a detector, a controller, and a neural network. The detector detects a joining state of a joining portion when work pieces are joined with each other. The controller controls the output of the joining equipment. In response to output signals from the detector, the neural network transmits signals to the controller. Such a structure allows the joining equipment to flexibly respond to complicated changes in joining states. Besides, using similarity with a thermal conduction equation enables to minimize the number of input items fed into the neural network. Furthermore, using an approximate solution to the thermal conduction equation realizes to accelerate the time for numerical calculation without loss of accuracy.

    摘要: The invention provides an electrothermal hot-melt type thermal transfer ink ribbon having a multi-layered structure used in thermal printers having a multi-stylus electrode head. Different from conventional ink ribbons of such a type composed of an electroconductive base film as a resistive layer, a vapor-deposited aluminum layer to serve as an electric pass to a return electrode and a layer of a hot-melt ink, the inventive ink ribbon has an additional layer as a heat barrier between the aluminum layer and the hot-melt ink layer so that the heat generated in the resistive base film and reaching the ink layer is radially diffused to produce a remarkable temperature gradient within the dot decreasing from the center to the periphery thus to provide a possibility of gradation control of the optical density of the printed dots by means of the voltage adjustment.

    摘要: In a device for reproducing the information, especially the video signal optically, magnetically or otherwise recorded on the spiral or concentric track on a disk-shaped recording medium, a control system for controlling the radially inward or outward shift or jump of a reproduction transducer from one track to another for effecting, in addition to the normal reproduction, the special effect reproductions such as still picture, slow, fast and reverse motions. The control system comprising a shifting means for shifting or jumping the transducer in the radial directions substantially perpendicular to the tracks, a control means for maintaining the transducer to scan the desired track, and a detecting means for detecting whether or not the transducer has been shifted or jumped and brought to the desired track and generating the output signal in response to which the shifting means is disabled to decelerate and stop the shifting or jumping of the transducer.
